Electrical life
The electrical life of a control unit is defined by the number of switching cycles under load reached or exceeded by 90% of all test items, with no repair or replacement of any part.
Electromechanical coupling relays
The electromechanical coupling relays imod and omod contain a high-quality card relay with the following features: better output-resistance characteristics than static coupling relays...
Electronics housing
The electronic enclosure product range consists of control cabinet enclosures, distribution enclosures and a mounting rail bus system (in-rail bus). Flexible electronics enclosures with widths...
Earth fault detection
Immediately or within the framework of cyclical self-monitoring, the unit assumes the agreed safe state after detection of the "earth fault" error.
Initial fault occurrence time (EEZ)
Time span in which the probability of the occurrence of a safety-critical initial fault is sufficiently low for the requirement class under consideration. The time span begins with the last time...
Extension modules
With the extension modules from Dold, you can simply multiply the output contacts of the basic modules in order to switch off any number of control circuits in a safety-oriented manner. These are...
